A
lift is used to direct or carry from a lower to a higher position. A hydraulic lift allows various components to be raised and/or lowered to various heights for a specific application or process. A hydraulic lift use the hydraulic technology of fluid motion to exert force required to move and lift heavy objects. Hydraulic lifts make use of
hydraulic cylinders in order to lower or raise work platforms or other types of lifting devices. Powered by fluid mechanics, hydraulic lifts help to lift, support, and move heavy objects that could not otherwise be moved by manual labor. That is why, hydraulic lifts are widely seen in the construction sites. They are used in varied industrial applications.
Types of Hydraulic Lifts
Depending on the applications, hydraulic lifts are of various types. Some of the most popular types of hydraulic lifts are as follows:
- Aerial lifts: Aerial lifts are used to lift workers or objects to dramatic heights that could not have been otherwise be accessed.
- Hydraulic Lift tables: Hydraulic lift tables are paltforms which are adjustable and can position work materials at accessible point beneficial to the worker.
- Vehicle Hydraulic Lifts: They help in the lifting of cars, and large vehicles for cleaning, and repairing.They can raise and lower vehicles like cars, SUVs. They can also transfer these vehicles to and from multiple elevations.
- Passenger Elevators: Used for lifting a large number of people in a residential complex or shopping malls and other commercial locations.
- Small hydraulic lifts: They are small objects making use of hydraulic mechanism like the brakes in the car or a hydraulic jack.
- Platform lifts: They are like the lift tables. The difference is that while the table in a lift table is used for carrying stronger and heavier loads, the platforms lift has large sized platforms.
- Rotary Lifts: They are used in the automotive industry. They are powered by hydraulics but like the normal lifts, they do not raising the item up from below, instead they lift up or hoist the object from above. Thay is why they are commonly used in the automotive repair industry, which help the car mechanics to check underneath the vehicles.
- Pallet lifts: These types of hydralic lifts are used for material handling and shipping applications requiring pallets. They can raise pallets from a ground position to a raised position.
Applications of Hydraulic Lifts
- Production facilities
- Multi-storey buildings
- Auto-repair shops
- Warehouses
- Docks
- Construction sites etc.
Careful Tips
- The lift needs to be operated by authorized professionals in the
use of hydraulic lifts and the positioning vehicles on lifts.
- The "dead stick" type controls should return to the
neutral or "off" position when released.
- The hydraulic pressure should never exceed the recommended level.
- The controls & equipments, pistons for dirt, damage and other
abnormal conditions need to be regularly inspected.
- The packing nuts and surface bolts around cylinders on hydraulic
hoists should be checked.
- The the hoist should be lubricated and checked for the tightness
of fasteners.
- The bent arms, cracks in welds or wear should be checked and
damaged parts replaced with the recommended ones.
- The lift area needs to be clean and free of oil, tools,
equipment, hoses, wires, etc.
- The weight of the vehicle should not exceed the lift capacity.
- The lift should not be used if it raises very quickly, jerks or
jumps when raised, slowly rises, either when in use or when not in
use, comes down very slowly, blows oil out of the exhaust line or
leaks oil at connections.
